Analysis of Roll Forming Process of Sheet Metal with Large Aspect Ratio Microgrooves Feature
摘要
Abstract
A new type of roll forming process is proposed,and a new design idea is proposed for the contour design of the main and auxiliary forming rollers,and the micro groove of TA1 titanium plate with a thickness of 0.1 mm(a depth of 2.5 mm,an aspect ratio of 86.2%).The roll forming test was carried out,and the maximum thinning rate and the maximum depth deviation were used as the evaluation indicators to verify the rationality and scientificity of the process.The results show that under the satisfying the deflection(<0.02 mm)of the auxiliary forming roller,the number of features of the auxiliary forming roller should be reduced as much as possible,so that the sheet is bent instead of drawing during the rolling of sheet metal,and its maximum thinning rate is less than 0.4%,and the depth deviation is less than 0.5%.With the stamping die,the micro grooves with large aspect ratio can be formed without the influence of the draft angle.This new forming process can promote the production of sheet metal micro-grooves.关键词
